Step 2-Transposition: This intermediate ciphertext then fills the columns (left to right) of a transposition matrix using the keyword crime". Since "crime" consists of 5 letters the matrix contains 5 rows. Note that the matrix is filled up w AAA at the bottom right with A D A The final cipher is read as rows based on alphabetical order of letters of the key "crime FVADA FXPFA AFDVA VAVGA XAFDD the recipient sets up two matrices based on two keywords, first to undo the transposition To decode, to undo the ADFGVX-substitution. Although this superencryption offers more security, it can be broken in s. First, the ADFGVX-substitution cipher has to be deciphered. Secondly, the remaining transpositions can step be undone by testing many possible transpositions Reference: ADFGVX Cipher - https://en.wikipedia.org/wiki/ADFGVX cipher //www.ti89.com/cryptot TASK 1 (15 points) Superencrypt "Abstractionism" by using keywords "Painter" for the ADFGVX substitution and "Kandinsky" for the transposition matrix TASK 2 (3 points) Please encrypt Claude Shannon's quote by using the given key "Information is the resolution of uncertainty Given key: n+2, n-1, nt1, n-2 Example: You will encrypt the word "Hello" by using the given key above into "JDMJQ SEE QUESTION ON (SIMILAR)
